Specific embodiment
In order to make the application the technical staff in the technical field be more clearly understood that the application, with reference to the accompanying drawing,
Technical scheme is described in detail by specific embodiment.
Server of the invention refers to the background server of net cast platform, such as the background server of XX live streaming.
Net cast platform is a kind of form of expression of server of the invention.
Client of the invention refers to client corresponding with user, is not to refer in particular to some equipment itself.Even
The same equipment, two users are logged on net cast platform respectively using different accounts, then being just referred to as respectively
Are as follows: the corresponding client of user 1 and the corresponding client of user 2 are seen as two different clients.And the same use
Family is logged on net cast platform respectively using two accounts, is also seen as two clients.That is, to this hair
For bright single user, user, account, the relationship of client are: 1 user, N number of account, N client, N are positive integer,
That is, 1 user can register with multiple accounts on direct broadcast service platform, each account corresponds to a client.
So the targeted user of the first client and the second client of the invention, it may be possible to the same person, it is also possible to be different
People.Certainly, for ease of description, the first client and the second client of the invention are corresponding is different user.This
In citing in invention, it is to use that it is user A, corresponding the second client (customer end B) that the first client (customer end A) is corresponding
Family B.
The main object of the present invention be to two videos make friends user when carrying out information exchange, guarantee interactive information
Secrecy and safety.Due to the particularity that video is made friends, so the safety of interactive information is even more important.
Firstly, each user logs on to Video service platform using corresponding client, Video service platform is to answer
Exist with the form of program, is a kind of form that server is presented, such as the application program etc. of live streaming class.
Secondly, it is non-right that server can utilize each client for logging on to net cast platform for server
Encryption Algorithm is claimed to generate a pair of of public, private key, different clients then generates different public, private keys.Not with symmetric encipherment algorithm
Together, rivest, shamir, adelman needs two keys: public-key cryptography (publickey) and private cipher key (privatekey).It is open
Key and private cipher key are a pair, if encrypted with public-key cryptography to data, could only be solved with corresponding private cipher key
It is close；If encrypted with private cipher key pair data, could only be decrypted with corresponding public-key cryptography.Because of encryption reconciliation
It is close to use two different keys, so this algorithm is called rivest, shamir, adelman.In the specific implementation process, when
After user logs on to server using client, server can verify the account, only legal registration user's ability
Normally log on to Platform Server.After login authentication success, server can then generate a pair of of public, private key, and server leads to public key
It crosses network protocol and is sent to the client, private key server is saved itself.For each Account Logon to server, clothes
Business device all takes identical strategy.It is implemented as follows:
Public, private key is generated using asymmetric arithmetic RSA herein.
RSA.CreatePairKey(SecretKey,PublicKey)；
Use RSA Algorithm next life private key KEY and public key KEY in a pair.
This public, private key is then a pair of of code key, wherein can be with public key come encryption data, with private key come ciphertext data.Service
Public key PublicKey can be then sent to the user by device.
When each client logs in, server can then generate respective a pair of of public, private key for each client, then
The public key of generation is sent to corresponding client.It for example, is the interaction schematic diagram of client and server referring to Fig. 1.
After first client (customer end A) and the second client (customer end B) log in platform, server meeting needle is utilized to customer end A
Corresponding a pair of of public key a private key a ' is generated, corresponding public key a is sent to customer end A.Server is for customer end B generation pair
Another pair public key b private key b ' answered, is sent to customer end B for corresponding public key b.These two pair public, private key is different.
When user searches video friend-making user by search, the interactive information that server can then make friends a pair of of video,
Other side is sent to after encrypting using the private key of other side.For example, the interactive information that customer end A is sent to customer end B makes
It is encrypted with the private key b ' of customer end B.Then, encrypted interactive information is sent to customer end B.It is carried out in customer end B
When decryption, there is the public key b that can unlock the encrypted interactive information due to there was only customer end B, so this user information exists
It when transmitting in network, even if being intercepted by hacker, also has no idea to decrypt, thereby may be ensured that in a pair of of video friend-making information
User information is the state of complete encipherment protection, and then guarantees the safety of information transmission.
Lower mask body introduces implementation process of the invention.
Referring to Fig. 2, the invention discloses one kind to carry out guard method, this method packet to privacy of user in Video chat
It includes:
Step 11, the interaction for carrying out Video chat interaction with the second client that the first client is sent is received to ask
It asks.
In the specific implementation process, it when the interaction request of the embodiment of the present invention can be Video chat and start, is searching
The interaction request generated when good friend；It is also possible to after becoming good friend, what when Video chat generated disappears for sending respectively chat
The interaction request of breath.
For example, when user A (that is: using the user of the first client) by video friend-making to search good friend when, such as it is logical
The pet name or other (such as: user location) are crossed to find matched video good friend user B (that is: using the use of the second client
Family) when, the first client can be generated according to the operation of user A for carrying out Video chat interaction with the second client (user B)
Interaction request, server then needs that the user information of user A is first sent the past according to the interaction request, and receives good friend
The user information of user B, if by mutual consent, so that matched two users can carry out Video chat.
Step 12, it is based on the interaction request, interactive information is added using second client corresponding private key
Close formation encrypted cipher text.
In the specific implementation process of the present embodiment, the interactive information that the embodiment of the present invention is mentioned is introduced first.
Interactive information, be the first client be sent to the second client for interaction information, divided according to type, including
But it is not limited to: the individual privacy sent when voice-enabled chat information, Video chat information, text chat information, request plusing good friend
Information etc..
And the particular content of interactive information, include but is not limited to be: the title of user, user UID (user identity card
Bright, User Identification), the gender of user, the hobby of user, user city, generate interactive information it is current when
Between stamp, chat content etc..
In these interactive information particular contents, for the UID of user, due to video make friends particularity, for
The privacy of user then needs more safeties and anti-harassment.And in video dating site, the UID of a user is then represented
The unique identification of one user, be it is fixed, can really indicate the information of the user.For example, first is after forum registers
UID23 is obtained, UID23 means that first.That second registration thereafter should be UID24, and UID24 means that second.
For so this UID once acquired in other side, other side has been known that the true UID of the user, then is likely at this
After chat terminates, chat is constantly harassed by other side in the case where user is not desired to contact again originally.So the present invention is real
It applies in example and the corresponding UID uniquely fixed of client is modified as temporary identifier (interim UID).That is, daily or every
Secondary chat server can all regenerate an interim UID to client, and the true UID of the interim UID and user is different, cannot
The truth for enough reacting user, is intended only as the mark of substitution, interim UID be it is variable, when each video interactive, service
Device can distribute interim UID (certainly, if the second client sends interactive information to send the first client of interactive information
When, server also can distribute interim UID for the second client).And then when video is made friends and is matched, user's in interactive information
UID is then to be replaced by interim UID, rather than the true UID of user, so that the true UID of user be hidden.And
What interim UID then always changed, then specific a certain individual is not corresponded to, and the safety of user is protected with this.
So using the corresponding private key of second client to interactive information carry out encryption formed encrypted cipher text it
Before, server can be handled the corresponding interactive information of the first client, in specific treatment process, generate described first
Client is used for and second client carries out the temporary identifier of Video chat interaction, the temporary identifier and first visitor
The unique user identity in family end proves that mark UID is different；Then the use of first client is replaced using the temporary identifier
Family proof of identification mark, and be added in the interactive information.In this way, which user's user identity in interactive information proves mark
UID has then been replaced by interim UID.
And for timestamp, the encrypted result of information can be made with more changeability, because of the first client pair
The user information answered will not change, and will not change so as to cause the result of encryption, and introduce time variable, then encrypted result is each
It will be variation, thus more safe.
So using the corresponding private key of second client to interactive information carry out encryption formed encrypted cipher text it
Before, server can determine whether that first client generates the current time stamp of the interactive information；The current time stamp is added
Enter in interactive information.
After introduction finishes interactive information, the present invention believes the interaction in the corresponding private key of the first client of server by utilizing
Before breath is encrypted, the first client can upload the interactive information to server, report interactive information to the mistake of server
Cheng Zhong, the first client are to be encrypted using corresponding public key, and then server is after receiving the interactive information,
It is to be decrypted using the corresponding private key of the first client.For example, when customer end A updates or report of user is personal
When information is to server, such as the location information or other information that report oneself, to server, customer end A then will use client
The corresponding public key of A is come to server is re-send to after information encryption, so only server just has the corresponding private key solution of customer end A
Close information out, to ensure safety of the information in network transmission process.
And during server for encrypting, will use the corresponding private key of the second client encrypts interactive information,
So being merely able to that interactive information is decrypted using the corresponding public key of the second client, even by hacker institute in decryption
Interception, also has no idea to decrypt, thereby may be ensured that the safety of the user information in a pair of of video friend-making information.
The corresponding private key of second client is that the non-encrypted algorithm of server by utilizing is generated for second client
, the private key that second client is exclusive.That is, the corresponding private key of the second client is that the second client is exclusive,
Other clients do not have, so even being that other clients have obtained the encrypted cipher text, can not decrypt, to guarantee interactive letter
Cease the safety of transmission.
As a kind of optional embodiment, in order to further ensure the safety of encryption, can using private key encryption it
Before, first interactive information is encrypted.In the specific implementation process, server receives the encryption that second client is sent
Key, and the interactive information is encrypted using the encryption key.Wherein, the encryption key is to belong to described second
The exclusive key of client.Specifically, encryption key is to be sent to server by the second client.So server exists
When sending interactive information, without retransmiting encryption key to the second client, the second client can call directly local add
It is decrypted close key pair, can be avoided transmission encryption key, and then reduce and be intercepted by a third party the risk usurped, further
Guarantee the safety of information transmission.Also, have since encryption key only has the second client and server, even if so encrypting it
Interactive information afterwards is obtained by other client, is also had no idea to decrypt, be thereby may be ensured that in a pair of of video friend-making information
User information safety.
As a kind of optional embodiment, the second client can not directly transmit encryption key, and only send coding
The coding rule of encryption key is to server.Specifically, in the corresponding private key of utilization second client to interactive information
It carries out encryption to be formed before encrypted cipher text, receives the first coding rule that second client is sent, and utilize described first
Coding rule generates encryption key, and is added using the encryption key that first coding rule generates to the interactive information
It is close.The advantage of doing so is that: firstly, the first coding rule is to be sent to server by the second client.So server exists
When sending interactive information, without retransmiting encryption key to the second client, the second client can call directly local the
One coding rule generates encryption key and it is decrypted, and can be avoided the first coding rule of transmission, and then reduce by third party
The risk usurped is intercepted, is further ensured that the safety of information transmission.Secondly as the first coding rule only have the second client and
Server just has, even if also having no idea to decrypt so the interactive information after encryption is obtained by other client, so as to
To guarantee the safety of the user information in a pair of of video friend-making information.
As a kind of optional embodiment, the interactive information is being carried out using second client corresponding private key
Encryption is formed before encrypted cipher text, and server is also based on the second coding rule and generates encryption key, and utilizes described second
The encryption key that coding rule generates encrypts the interactive information；Second coding rule is sent to described second
Client.Second coding rule is that the coding rule that server is determined is used to encrypt interactive information.So transmitting
Encrypted interactive information is given after the second client, can also transmit the second coding rule to the second client, so that the second visitor
Family end can generate corresponding decruption key according to the second coding rule and encrypted interactive information is decrypted.Therefore, even if
It is that other clients have got encrypted interactive information, not obtaining the second coding rule is also that can not decrypt to it,
And then it can be further ensured that the safety of information transmission.
After encryption is completed, then next step can be carried out.
Step 13, the encrypted cipher text is sent to second client, so that second client utilizes and institute
The corresponding public key of private key is stated to be decrypted.
And during decryption, firstly, the public key that the embodiment of the present invention is mentioned, is non-right described in the server by utilizing
Claiming that algorithm generates for second client, second client is exclusive and corresponding with private key public key.
Secondly, being be directed to the generation of the second client using server one during the second client is decrypted
Public key in private-public key is decrypted, since the private-public key is a pair of, and is that the second client is exclusive, so only
There is the second client that the encrypted cipher text can be decrypted.
Since the first client and the second client are actually the process of information exchange, so the second client can also be with
The first client is sent messages to, is then decrypted by the first client.In the process, the second client is sending message
It when to the first client, is sent after being encrypted by the public key of the second client, the second client of server by utilizing
Message is decrypted in corresponding private key.Thereafter, the corresponding private key of the first client of server by utilizing encrypts the message,
It is then forwarded to the first client, and then it is right to can use itself after receiving the message after the encryption for the first client
It is decrypted in the public key answered.
As an example it is assumed that user A (using customer end A) and user B (using customer end B) are matched, first to be regarded
Frequency is chatted, then both sides require to receive the user information of other side.
Firstly, user information is packaged.In video friend-making, both sides is needed to intercourse user information.Specifically
User information includes, the title of user, the interim UID of user, the gender of user, the hobby of user, user city, it is current when
Between stab etc. information be packaged together.
Secondly, being encrypted together to user information Introduction Time stamp.
In the process of encryption:
Introduction Time stamp of the present invention can then make the encrypted result of information with more changeability, because user information will not
Variation, will not change so as to cause the result of encryption, and introduce time variable, then encrypted result can be variation every time, from
And it is more safe.
It is directed to citing of the invention, user A and user B carry out Video chat.Customer end A is needed the user of user A
Information is sent to customer end B, and customer end B needs the user information by user B to be sent to customer end A.
When the user information of user A is sent to customer end B by customer end A, the private key that server then will use customer end B adds
The user information of close user A, and encrypted user information is sent to customer end B, so that only customer end B just can be carried out solution
It is close.
And customer end B is when being sent to customer end A for the user information of user B, then server then will use customer end A
The user information of private key encryption user B, and the user information of encryption is sent to customer end A, so that only customer end A could be into
Row decryption.
It is implemented as follows:
For the ciphering process of the user information of user A:
EncryptUserInfoA=RSA.Encrypt (UserInfoA+Time, BSecretKey)；
It is then the user information UserInfoA of user A herein, in addition timestamp information Time, then using customer end B
SecretKey encrypts information.Customer end B is then sent to after encryption.
Similarly for the ciphering process of the user information of B:
EncryptUserInfoB=RSA.Encrypt (UserInfoB+Time, ASecretKey)；
It is then the user information UserInfoB of user B herein, in addition timestamp information Time, then using customer end A
SecretKey encrypts information.Customer end A is then sent to after encryption.
Since public key is different for each client, and private key only has server to have, so personal user information
In a network transmission be safe, and being trapped without corresponding private key KEY decryption then can not also crack it is therein
Cleartext information.
So far, it is achieved that after being encrypted for user information using the private key of reciever and is sent to other side's use mutually
Family.
And during decryption:
When user, which is matched to corresponding user, carries out Video chat, then it will receive the user information that server issues, it is first
First user can then be decrypted information, to obtain the cleartext information of the other user.It is implemented as follows:
For user when logging in, server is then handed down to one public key KEY of client.
Assuming that customer end A receives the user information of user B.
UserInfoB=RSA.Decrypt (EncryptUserInfoB, APublicKeyKey)；
So customer end A user information that the user B of encryption is then decrypted with the public key APublicKeyKey of oneself, from
And obtain the user information of the user B of plaintext.
So far, it is achieved that the operation that the user information for the other side that server issues is decrypted user.
Based on unified inventive concept, the invention also discloses one kind to carry out protection dress to privacy of user in Video chat
It sets.
Referring to Fig. 3, the inventive system comprises:
Receiving module 31, for receiving being used for and the progress Video chat interaction of the second client for the first client transmission
Interaction request；
Encrypting module 32 believes interaction using the corresponding private key of second client for being based on the interaction request
Breath carries out encryption and forms encrypted cipher text；Wherein, the corresponding private key of second client is the non-encrypted algorithm needle of server by utilizing
